At Permax Roofing, we believe in transparency. This guide breaks down exactly where your money goes, so you can budget with confidence.

The “Per Square” Pricing Model

First, you need to speak the language of roofers. Contractors don’t quote by the “square foot”; they quote by the “Square”.

• 1 Square = 100 square feet.

• The average US roof is about 17 Squares (1,700 sq. ft.).

Cost Breakdown by House Size

The size of your home is the biggest cost factor. Below are the estimated ranges for a full replacement using standard Architectural Asphalt Shingles (the most common choice in the US).

⚠️ Note: These numbers are for simple gable roofs. If your roof has multiple chimneys, dormers, skylights, or a steep pitch, expect labor costs to increase by 15-25%.

4 Hidden Costs That Surprise Homeowners

When you get a quote, make sure it includes these often-overlooked items. A low-ball bid might exclude these, leading to surprise bills later.

1. Tear-Off & Disposal:
   Does the quote include removing the old roof? Layering new shingles over old ones is cheaper but not recommended (it shortens the lifespan and may void warranties). Disposal fees usually run $1,000 – $3,000.

2. Rotten Decking:
   Once the old shingles are off, contractors might find rotten plywood underneath. This is impossible to predict perfectly. Budget an extra $500 – $1,000 for wood replacement just in case.

3. Permits:
   Local building permits are mandatory. They typically cost $150 – $400, depending on your municipality.

4. Ice & Water Shield:
   In colder climates, code requires a special waterproof barrier at the eaves. Ensure this is listed in your contract.

Pro Tip: If you plan to stay in your home for 20+ years, Metal is the cheaper option in the long run. If you plan to move in 5 years, stick with Asphalt.

DIY vs. Hiring a Pro: Is It Worth the Risk?

We see many homeowners trying to save money by doing it themselves. While you save on labor costs (about 60% of the total price), the risks are massive:

• Warranty Void: Manufacturers like GAF or Owens Corning will void material warranties if not installed by a certified pro.

• Safety: Falls from roofs are a leading cause of injury.

• Mistakes: Improper flashing around chimneys is the #1 cause of leaks.

Our Advice: Don’t gamble with your home’s structure. The money you save on labor can be wiped out by a single water damage claim.

Conclusion: How to Get the Best Price

The roofing market is competitive. Prices for the exact same job can vary by $2,000 or more between different companies.
